vim-patch:9.1.1476: missing out-of-memory checks in cmdexpand.c (#34624)
Problem: missing out-of-memory checks in cmdexpand.c
Solution: add missing out-of-memory checks, re-order code
(John Marriott)
This commit does the following:
- in cmdline_pum_create() add out-of-memory check call of ALLOC_MULT()
- in expand_cmdline() move check for out-of-memory to cover both
assignments of file_str
- in nextwild() don't free `p2` until after it's last use.
